Abstract (en)
[origin: EP1873906A2] A bias control signal generation unit (1) detects ON and OFF of a transmission signal input to an amplifier (2) and having a property of a burst according to burst information. The bias control signal generation unit (1) controls a bias voltage to be applied to an amplifier (2) such that an idle current flowing through the amplifier (1) can be flowing in a larger amount in a transmission OFF period, and can return to a normal level in a transmission ON period.
